Psalm 8:2
Holman Christian Standard Bible
2 Because of Your adversaries,
You have established a stronghold
from the mouths of children and nursing infants,
to silence the enemy and the avenger.
Psalm 28:8
New American Standard Bible
8The LORD is their strength,
And He is a saving defense to His anointed.
A decree is defined as an order usually having the force of law; to command or enjoin; having the force of a law enacted by the legislature. So what does that mean to you? God has given you dominion and power because you are His. Even if you are a babe in Christ, you can speak in the name of Jesus and it will silence the enemy and the avenger. The enemy is constantly scheming on you. You no longer belong to him and he's furious. He comes like a roaring lion trying to devour you. But a decree will stop him. You can command the enemy to get behind you. Use the law given to you which is the word of God. Things have to change when you speak the Word.
You have the power to establish a stronghold because of who you are. A stronghold is not always a negative thing. A stronghold is a a fortified place, a place of security or survival, a place dominated by a particular group or marked by a particular characteristic. God is your defense, your security. He is a hiding place from the enemy and the issues of life. He is your strength and you are His anointed one.
It may sound simple, but a decree will stop the enemy.
God Bless
